Abstract
A lighting control system includes a plurality of luminaires each having a selectively powerable first light source and a selectively powerable second light source. The luminaires are powerable and controllable by a common AC power source. A signal receiving controller of each of the luminaires is electrically connected to the first light source and the second light source and selectively causes power to be routed to either the first light source or the second light source dependent on a control signal sent via the AC power source.
Claims20
A lighting control system comprising:
- a plurality of luminaires powerable and controllable by a common AC power source, each of said luminaires having
- at least one selectively powerable HID lamp,
- at least one selectively powerable LED light source;
- HID electronics electrically connected to said HID lamp and selectively electrically connected to said AC power source;
- LED electronics electrically connected to said LED light source and selectively electrically connected to said AC power source;
- and
- a signal receiving controller electrically connected to said HID electronics and said LED electronics, said signal receiving controller having a power source input selectively electrically connected to said AC power source;
- wherein each said signal receiving controller selectively causes said AC power source input to be supplied to either said HID electronics or said LED electronics;
- a lighting controller electrically coupled with said AC power source remote from said plurality of luminaires;
- wherein said lighting controller is configured to pulsingly decrease and increase the voltage between said AC power source and said power source input of said signal receiving controller of a plurality of said luminaires, thereby causing a control pulse signal to be generated at said power source input of each said signal receiving controller of a plurality of said luminaires;
- and
- wherein said signal receiving controller of each of said luminaires is configured to recognize said control pulse signal at said power source input and after recognition of said control pulse signal to cause an alternate of said HID electronics and said LED electronics to be routed with said AC power source input.
A lighting control system comprising:
- a plurality of luminaires, each of said luminaires being coupled to a pole and having
- a primary light source housing coupled to said pole;
- at least one selectively powerable HID lamp enclosed in said primary light source housing and electrically connected to an HID ballast, said HID lamp selectively producing a directed HID light output;
- a longitudinally extending LED arm assembly extending from the pole, said LED arm assembly having a selectively powerable secondary LED light source coupled thereto, said LED light source having a plurality of LEDs electrically connected to at least one driver and selectively producing a directed LED light output;
- wherein the luminosity of said HID light output is at least two times greater than the luminosity of said LED light output;
- a signal receiving controller electrically coupled to an AC power line, said at least one HID ballast, and said at least one driver;
- wherein said signal receiving controller is operable to electrically route said AC power line to either said at least one HID ballast or said at least one driver dependent on an electrical signal sent over said AC power line.
A lighting control system comprising:
- a plurality of luminaires powerable and controllable by a common AC power source, each of said luminaires having
- at least one selectively powerable first light source having associated first electronics for powering said first light source,
- at least one selectively powerable second light source having associated second electronics for powering said second light source,
- wherein the power consumption of said first light source is at least two times greater than the power consumption of said second light source, and
- a signal receiving controller electrically connected to said first electronics and said second electronics, said signal receiving controller having a power source input selectively electrically connected to said AC power source,
- wherein each said signal receiving controller selectively causes said AC power source input to be routed to either said first electronics or said second electronics;
- a lighting controller electrically coupled with said AC power source remote from said plurality of luminaires;
- wherein said lighting controller is configured to pulsingly remove and restore the connection between said AC power source and said power source input of said signal receiving controller of a plurality of said luminaires, thereby causing a control pulse signal to be generated at said power source input of said signal receiving controller of a plurality of said luminaires;
- and
- wherein said signal receiving controller of each of said luminaires is configured to recognize said control pulse signal at said power source input and after recognition of said control pulse signal to cause an alternate of said first electronics and said second electronics to be routed with said AC power source input.
